Somehow this becomes more and more complicated.

Can we use some simpler solution - like when packet flags & 2 and there was
no remaining_len before it (i.e. we are not inside partial packet)
nor after it (i.e. we were not reading start of partial packet, but maybe
this condition can be omitted) then add this packet to index.

Passing two additional arguments for getting data to index does not seem right.
